 Passing null or not is now triggered by whether setting the parameter was called at all.  In other ords a distinction is made between calling `setParameter` passing null versus not calling `setParameter` at all.  In the first case, we pass along the null value; in the second we do not.
 
+=== Query
+
+=== HQL results
+
+Hql queries that joins an Entity `Person` with an Entity `Address` without specifying a select clause `from Address a join a.address` does not return anymore a `List<Object[]>`but a list of `Person`.
+
+The hql query `select a,ad from Address a join a.address ad` returns instead a `List<Object[]>`.
+
+e.g.
+```
+@Entity
+class Person {
+    ...
+
+    @ManyToOne
+    Address address
+
+    ...
+}
+
+@Entity
+class Address {
+
+    ...
+
+}
+
+List<A> result = session.createQuery("from Address a join a.address").list()
+
+```

+
+==== Iterate
+
+The `Query#iterate()` method has been removed.
